Radioactive zinc ( sup 65 Zn), zinc, cadmium, and mercury in the Pacific Hake, Merluccius productus (Ayres), off the West Coast of the United States

Description: The Pacific Hake, Merluccius productus (Ayers) was used to monitor the waters off Puget Sound and the West Coast of the US for zinc(Zn), cadmium(Cd), mercury(Hg) and {sup 65}Zn. The Columbia River is not the source of Zn, Cd or Hg contamination, but is the source of {sup 65}Zn, with the concentration in the Hake reflecting the position of the Columbia River plume. Zn and Cd accumulation in the Hake were fit to the equation Y=B{sub 1}+B{sub 2}e{sup B}{sub 3}X where Y is the concentration of the … more

Preliminary safety analysis of the B-C Cribs Controlled Area. [Hanford Reservation]

Description: Approximately 2,000 acres of land in the center of the Hanford Reservation is contaminated with an estimated 14 Ci of /sup 137/Cs and 81 Ci of /sup 90/Sr associated with animal wastes. Approximately half of this activity is located on (or within) 2.5 centimeters of the ground surface. The source of the contamination was the B-C Cribs and trenches which were used as liquid radioactive waste disposal sites during the 1950's. The mechanism for movement of radionuclides from the disposal site to th… more

Energy and environment annual report 1974. [Environmental Research programs]

Description: Research in the Division's environmental science program includes air pollution, water pollution, and the effects of pollutants on man and natural ecosystems. Work has focused on the chemistry and physics of particle surfaces. Using the technique of electron spectroscopy for chemical analysis (ESCA), surface reactions of sulfur and nitrogen compounds have been studied, and results include the identification of new chemical forms of nitrogen on particle surfaces and evidence for the importance o… more

Environmental and technological implications of a theta-pinch fusion power plant

Description: The environmental effects of this conceptual design were evaluated and found to be little different from other electrical power plants in most regards. Exceptions include a very small release of tritium, a low-hazard isotope, and relatively large amounts of radioactive material which must be either stored on site for eventual reprocessing or permanently discarded. These radioactive materials are nonvolatile and should not pose a difficult disposal problem, although some of the material may rema… more

Soil burial of radioisotopic fuel capsules

Description: From thirteenth international conference on thermal conductivity; Lake Ozark, Missouri, USA (5 Nov 1973). The safe burial in soil of a radioisotope heat source is an extremely complex problem, influenced by many parameters, including soil particle size, moisture content, weathering, density, inhomogeneities such as rocks and vegetation, soil disturbance upon impact, soil composition, and location on the earth. Precise descriptions of an accidental burial environment are in general impractical, … more

Preliminary safety analysis report for the PNL Neutron Multiplier Facility

Description: The design, operation, and safety of the Neutron Multiplier Facility (NMF) at the Pacific Northwest Laboratories are discussed. The NMF will provide thermal neutrons for irradiation of two basic types of samples, i.e., environmentai samples and a 4 gram maximum sample of fully enriched uranium. The latter will be used to produce fission products for on-line mass spectrometry. The Neutron Multiplier will produce thermal neutrons by fission multiplication and subsequent moderation of neutrons fro… more

Duct Gas Cooling Model

Description: The work reported here was motivated by a fire safety plan proposed by H.A. Lee for glove boxes, hoods, or other enclosures which contain radioactive or other toxic materials.
